Pelagia Testnet

Learn how to connect to and deploy on Reef Pelagia, the next-generation Reef Chain testnet.

What is Pelagia?#

Reef Pelagia is the new Reef Chain testnet representing the core blockchain upgrade currently in progress. It is intended as a stress-test and feedback environment for developers before changes are promoted to mainnet.

Pelagia was first opened to hackathon participants at Web3Conf Enugu 2025 (September 20–27, 2025), where multiple projects successfully deployed to it during the event.
